/* An exception is an event that can be signaled from within a
|
|
|
|
|
|
function. This event can then be "caught" or "trapped" by the
|
|
|
|
|
|
callers of this function. This potentially allows program flow to
|
1997-12-07 01:31:01 +01:00
|
|
|
|
be transferred to any arbitrary code associated with a function call
|
1996-09-15 02:47:01 +02:00
|
|
|
|
several levels up the stack.
|
|
|
|
|
|
|
|
|
|
|
|
The intended use for this mechanism is for signaling "exceptional
|
|
|
|
|
|
events" in an out-of-band fashion, hence its name. The C++ language
|
|
|
|
|
|
(and many other OO-styled or functional languages) practically
|
|
|
|
|
|
requires such a mechanism, as otherwise it becomes very difficult
|
|
|
|
|
|
or even impossible to signal failure conditions in complex
|
|
|
|
|
|
situations. The traditional C++ example is when an error occurs in
|
|
|
|
|
|
the process of constructing an object; without such a mechanism, it
|
|
|
|
|
|
is impossible to signal that the error occurs without adding global
|
|
|
|
|
|
state variables and error checks around every object construction.
|
|
|
|
|
|
|
|
|
|
|
|
The act of causing this event to occur is referred to as "throwing
|
|
|
|
|
|
an exception". (Alternate terms include "raising an exception" or
|
|
|
|
|
|
"signaling an exception".) The term "throw" is used because control
|
|
|
|
|
|
is returned to the callers of the function that is signaling the
|
|
|
|
|
|
exception, and thus there is the concept of "throwing" the
|
|
|
|
|
|
exception up the call stack.
